Notes

• Many Jain names are Sanskrit in origin and emphasize inner virtues like peace, contentment, and joy.
• If you’d like names drawn from specific Jain tirthankaras or Digambar/Shwetambar preferences, tell me and I can tailor the list.
• I can also provide short pronunciations or highlight any potential cultural cognates if you’re aiming for a particular community or region.
